Failure

Pei Ling watched as he walked to the furnace in the alchemy room. He formed hand seals skillfully, drew out the Nine Nether Fire from the talisman, and lit the furnace.

While the furnace was heating up, the system began to process the medicinal herbs.

First was the Ghost Placenta.

Pei Ling had already experienced the power of this material yesterday. It was naturally capable of attacking the soul. However, in front of the system, its impact was useless. Soon it was cleaned up and thrown into the furnace.

Following that was Frost Iron Grass. As its name suggested, Frost Iron Grass was like a ball of cold iron wire. It did not look like grass at all.

He needed to nurture it a little with his spiritual power before it would melt into liquid form.

According to the instructions given by Yan Gu, dealing with the Frost Iron Grass was not difficult. The difficult part was the meticulous control of spiritual force.
